Hi Manolo,
Glad I could help, and I appreciate your response

With the study of ethnographic weapons, the presence of many European trade and military blades is almost standard. In Saharan regions many French military blades from occupational forces found thier way into native hilts throughout the 19th century. In my opinion, this adds so much more dimension to the heritage of these weapons and makes them all the more fascinating!
All the best,
Jim
